Does it account for Daylight Saving Time?

Yes, our converter uses the IANA timezone database, which includes all current DST rules for every timezone in the world.

UTC (Coordinated Universal Time) is the primary time standard by which the world regulates clocks. All timezones are defined as offsets from UTC.

Can I compare multiple timezones at once?

Yes, you can add multiple cities or timezones and see the equivalent times side by side.

How many timezones are there in the world?

There are 38 distinct UTC offsets in use, ranging from UTC-12 to UTC+14. This includes half-hour (UTC+5:30 India, UTC+9:30 Australia) and 45-minute offsets (UTC+5:45 Nepal, UTC+8:45 Australia).

What is the International Date Line?

The International Date Line (IDL) runs roughly along the 180° meridian in the Pacific Ocean. When you cross it westward, you gain a day; crossing eastward, you lose a day.

Why do some timezones have 30 or 45 minute offsets?

Countries chose offsets that best matched their solar noon. India uses UTC+5:30 and Nepal uses UTC+5:45 because standard hourly offsets didn't align well with their geography.

Which country has the most timezones?

France has the most (12 timezones) due to overseas territories. Russia spans 11 timezones. The US has 6 (including Hawaii and Alaska).

Why people convert NST to Hong Kong time

Scheduling a call from NST to Hong Kong: a 10:00 AM start in NST lands at 9:30 PM in Hong Kong, so you can confirm the slot without doing the arithmetic yourself.
Handling a +11h 30m gap: NST and Hong Kong have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Hong Kong is 8:30 PM in NST.
Booking travel or deliveries: tracking Hong Kong local time against NST keeps pickup windows and arrival estimates honest across the +11h 30m offset.

Always state the zone abbreviation, not just the hour. "3:00 PM NST" is unambiguous; "3 PM" across a +11h 30m gap is not.
With a +11h 30m gap there is no shared 9-to-5 window, so alternate the early start: one week NST takes the early slot, the next week Hong Kong does.

About NST (Newfoundland Standard Time)

Newfoundland Standard Time (NST) is one of the few half-hour offset time zones in the world. It covers the island of Newfoundland in Canada and is 30 minutes ahead of Atlantic Standard Time. This unique offset exists because Newfoundland was an independent country until 1949.

About HKT (Hong Kong Time)

Hong Kong Time (HKT) is fixed at UTC+08:00 all year and does not observe daylight saving time. Hong Kong last used summer time in 1979 and has kept a single offset since. HKT shares the UTC+08:00 offset with China Standard Time, Singapore Time, Malaysian Time, Philippine Time and Australian Western Standard Time, but is listed separately because Hong Kong maintains its own timekeeping authority. As a major financial centre, Hong Kong's trading hours set the rhythm for markets across Asia, opening at 09:30 HKT which is 01:30 in London and 20:30 the previous evening in New York.

Best time to call between NST and Hong Kong

With a +11h 30m offset there is no overlap inside a normal 9 AM – 5 PM day. Hong Kong opens at 9:00 AM HKT, which is 8:30 PM in NST, so real-time calls need an early-morning or late-evening slot on one side.

Business hours overlap

NST and Hong Kong have no shared working hours because of the +11h 30m gap. Teams need to alternate early starts or rely on asynchronous handovers.

NST is 11 hours 30 minutes ahead of Hong Kong (NST UTC-03:30 → HKT UTC+08:00). There is no shared 9-to-5 window, so plan around an early or late slot. Remember to re-check around daylight-saving transitions.
